A-site-ordered perovskite oxides with formula AA'3B4O12 have a rich variety of physical and chemical properties. Most have Jahn-Teller active Cu2+ or Mn3+ at the square-planar...

We plan to investigate the low-temperature structure and magnetostructural coupling in PdCrO2, which is a quasi-2D material with strongly anisotropic physical properties. It is...

The proposal aims at revisiting the properties of disordered, nano-sized and structurally dynamic delta-MgCl2 particles as fundamental components of Ziegler-Natta (ZN) catalysts...

Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a...

Hertbertsmithite ZnCu3(OH)6Cl2 is a model S =1/2 kagome antiferromagnet, received much attention last years. From recent studies a sign of a nearby quantum phase transition...

The metal-organic framework perovskite analogue guanadinium copper(II) formate has achieved considerable recent attention for its multiferroic properties and consequent...

The search for new porous materials is increasingly be driven by socio-economic pressure to diversify our energy supply and minimize environmental impact. Carbon-based...

The exotic physics of low-dimensional quantum magnets has recently been highlighted by the award of a Nobel Prize to Duncan Haldane. We have identified the molecular framework...

Quantum spin liquids are exotic states of magnetic matter in which conventional magnetic ordering is suppressed. Magnetic analogues of ice are good candidates to observe this...

The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the...

The National Physical Laboratory (NPL) and the WISH instrument team has worked together to enable simultaneous real-time high resolution (powder and single crystal) neutron...

Dy3Mg2Sb3O14 forms a layered structure with magnetic Dy3+ ions forming sheets of corner sharing triangles, called a Kagome lattice. The Ising magnetic moments are constrained to...

We propose elastic neutron powder diffraction experiments on perovskite antimonates (Ba,K)SbO3. Main-group oxide perovskites have attracted intense research interest due to...

The interface between nickel bismuth layers is widely reported to be superconducting and due to the proximity of ferromagnetic and high spin-orbit-coupling layers, it is...

A recent exciting development in magnetic materials was the discovery of a new iron oxide, Fe4O5, using high temperature and high pressure. A very recent structural study has...

The modified pyrochlores AM2+M3+F6 (A alkali metal ion, M transition metal ion) are a class of highly frustrated materials that have a randomness associated with the positions...

Colossal magnetoresistance (CMR) is observed in the oxypnictide NdMnAsO1-xFx (x = 0 - 0.085) at low temperature. The CMR in NdMnAsO1-xFx arises due to competition between a...

Incommensurate magnetic phases generated by frustrated magnetic exchange interactions can stabilise novel induced magnetoelectrics. We have recently found that the...

We have observed an anomalous monotonically increasing longitudinal field relaxation rate in LiY_(1-x)Ho_xF_4 for applied fields above 1000 G (along the c-axis) and at a...

Our picture of the structure of organic solids is derived almost exclusively on ?conventional? crystal structures based on Bragg scattering. Though it is hard to overstate the...
